Before the gang meets him, Taylor was used to the mountain Pokémon coming down and taking Berries from him when they were hungry. But now, a group of wild Aipom (which included a future capture), plus other variousmonkeytypes, are constantly coming to pillage his Berries for the "Mountain King" (in reality a Slaking mecha operated by Team Rocket).

Taylor helps the kids along in getting their lost effects back, and in the end, gets his Berries back as well, with the aid of the other mountain Pokémon that stole them in the first place.
